respective pairs beyond its opposite ends, or beyond the platformsforming such ends, whereby when a train of cars is equipped with myimprovement the recess in the head of each beam 5 on one car willregister with a wedge, 12 on a head on an opposing car; and the extentof projection of the heads is such as to cause the opposing recesses andWedges to lap one another to a considerable distance in the normalextent of separation of the opposing car platforms. The space betweenthe surfaces of the recesses and wedges is ample to avoid anyobstruction to the normal vertical oscillations of the platforms in therunning of the train; and the recesses being open-sided they permit freetransverse movement of the wedges through the recesses under the lateralswaying of the cars, in running and rounding curves, while the opposingwedges and recesses always re main in their mutuallydapping relationunder normal conditions, ready to subserve their cooperating purposewhen the cars are forced one against the other, as in a collision. hen acollision occurs, the opposing heads, at the ends of adjacent cars, areforced together, causing the wedges, by their wedging engagement withthe recesses, to securely hold the platforms in alinement and preventthe climbing of one car by another and resultant telescoping of one bythe other. The force of the collision enters the wedges fully into therecesses, when the shoulders 12 abut against the outer ends of therecessed heads and further increase the strength of their interlockingengagement.

The particular shape shown and described of the recess and wedge of theopposing heads best serves the purposes of my improvement, though it isnot intended to limit my invention thereto, except in such of theappended claims as specify that shape.

To all whom it may concern.-

Be it known that I, JAMES S. THOMPSON, a citizen of the United States,residing at Chicago in the county of Cook and State of Illinois, haveinvented a new and useful Im provement in Antitelescoping Devices forRailway-Cars, of which the following is a specification.

My invention relates to an improvement in the class of devices used asextensions at the ends or platforms of railway-cars to prevent them fromtelescoping in the event of collision.

The object of my improvement is to provide a construction of the meansemployed for the aforesaid purpose whereby their effectiveness shall bematerially increased and whereby they shall afford full freedom of playto lateral swaying of the cars in motion and in rounding curves withoutimpairing their operation.

In the accompanying drawings, Figure l is a broken plan View of theunder-framing of the bodies of two coupled railway-cars provided with myimprovement; Fig. 2 is a section on line 2, Fig. 1, and Fig. 3 is an endview of the under-framing of one of the cars of Fig. 1.

At each side of the longitudinal center of the under-framing 4 of arailway-car extend two substantial beams 5 and 6, of rectangularcross-section, which occupy the positions of and may supplant the sillswhich usually support the platform-work 7 at the uppermost of the seriesof steps. At their rear ends the two beams may be socketed into thebody-bolster 8, and they are securely fastened between their ends to theframing, as shown. The forward ends of the beams project beyond theplatform in the plane of the draw-bar, the yoke-support for which isrepresented at 9, Fig. 3. The projecting end or head of the beam 5contains a V-shaped What I claim as new and desire to secure recess 11essentially extending from side to by Letters Patent is: side throughthe head to render the recess 1. In combination with a railway-car,anopen-sided. The corresponding end or head titelescoping meanscomprising heads proof the beam 6 terminates in a wedge 12 of jectingbeyond the end of a car at opposite V-shape extending preferably frombetween sides of the longitudinal center of its base, shoulders 12 onthe end of the beam to one of said heads containing an open-sidedregister with the shoulders of the recess in recess and the other headhaving a wedge the head of the opposing beam, this wedge extending fromit, for the purpose set forth. being of dimensions corresponding with 2.In combination with a railway-car, anthose of the recess. titelescopingmeans comprising heads pro- Two pairs of the beams 5 and 6 areprojecting beyond the end of a car at opposite vided on the car toprotrude the heads of the sides of the longitudinal center of its base,
